Chapter 2 Quick Guide
This chapter is intended to help you grasp the basic operations of the SMG analog gateway in the
shortest time.
Step 1: Confirm that your packing box contains all the following things.
SMG Series Analog Gateway *1
Angle Bracket *2, Rubber Foot Pad *4, Screw for Angle Bracket *8
220V Power Cord *1
Warranty Card *1
Installation Manual *1
Step 2: Properly fix the SMG analog gateway.
If you do not need to place the gateway on the rack, simply fix the 4 rubber foot pads. Otherwise,
you should first fix the 2 angle brackets onto the chassis and then place the chassis on the rack.
Step 3: Connect the power cord.
Make sure the device is well grounded before you connect the power cord. Check if the power
socket has the ground wire. If it doesn’t, use the grounding stud on the rear panel of the device
(See Figure 1-3) for earthing.
Step 4: Connect the network cable.
Step 5: Connect the telephone line. The line from PSTN should be connected to FXO port
(port with red LED flashing); the line from station should be connected to FXS port (port
with green LED flashing).
The connection for SMG1008, SMG1016, SMG1032 series products:
These series products provide RJ11 interfaces. You can use a common telephone line directly or
construct a telephone line by yourself according to Figure 2-1. Note that only the middle two cores
in the RJ11 jack are valid for use.
Figure 2-1 RJ11 Connection
The connection for SMG1032A2 series product:
SMG1032A2 adopts two RJ21 interfaces each of which accommodates 16 channels. One
corresponds to channels 1 through 16 and the other corresponds to 17 through 32. Each pin in
the RJ21 connector functions as follows.

in again.
Step 8: Modify IP address of the gateway.
You can modify the IP address of the gateway via ‘System Tools Network’on the WEB interface
to put it within your company’s LAN. Refer to 3.9.2 Network for detailed instructions about IP
modification. After changing the IP address, you shall log in the gateway again using your new IP
address.
Step 9: Make phone calls.
Note: For your easy understanding and manipulation, all examples given in this step do not
involve registration, that is, SIP initiates calls in a point-to-point mode.
Situation 1: Call from a station to another (TelTel)
The gateway allows two FXS ports to call each other by default. Just use a station connected with
an FXS port to dial the number of the destination FXS port and you can make a TelTel call. The
default number of an FXS port is 80XX, among which XX represents the corresponding port
number. For example, the default number corresponding to Port 1 is 8001, and that corresponding
to Port 32 is 8032.
Actually a TelTel call on the gateway is accomplished via the routing of TelIPIPTel. For
detailed introductions and configuration guide, refer to Q2 in Appendix B.
Situation 2: Call from a station to an IP phone (TelIP)
1. Go to ‘Advanced Settings Dialing Rule’ on the WEB interface and click the ‘Add New’
button to add a new dialing rule. Refer to 3.5.9 Dialing Rule for detailed instructions. Enter
either a particular number or a string of ‘x’s to represent several random numbers. For
example, ‘xxx’ denotes 3 random numbers. You may use the default value of ‘Index’ and are
required not to leave ‘Description’ empty.
Example: Set Index to 99, fill in Description with test and configure Dial Rule to 123.
2. Go to ‘Port Settings Port Group’ on the WEB interface and click the ‘Add New’ button to
create a new port group and add FXS ports which are connected with stations to it. Refer to
3.6.3 Port Group for detailed instructions. You may use the default values of other
configuration items and are required not to leave ‘Description’ empty.
Example: Provided the FXS port which is connected with a station is Port1, check the
checkbox before Port1, set Index to 1, fill in Description with test, and keep the default
values of other configuration items.
3. Go to ‘Route Settings TelIP’ on the WEB interface and click the ‘Add New’ button to add
a new routing rule. Refer to 3.7.3 TelIP for detailed instructions. Select the port group
created in Step2 as ‘Source Port Group’ and fill in ‘Destination IP’ and ‘Destination Port’ with
the IP address and the Port number you plan to call. You may use the default values of other
configuration items and are required not to leave ‘Description’ empty.
Example: Provided the remote IP address intended to call is 192.168.0.111 and the port is
5060. Set Index to 63, Source Port Group to 1, fill in Description with test, configure
Destination IP to 192.168.0.111, Destination Port to 5060, and keep the default values of
other configuration items.
4. Pick up the station and dial the number set in Step1 to ring the remote IP phone. If you have
set a particular number in Step 1, only this number you can dial; if you have set a string of ‘x’s,
how many ‘x’s there are, how many random numbers you can dial.
Example: Pick up the station and dial 123. Then the IP phone with the IP address
192.168.0.111 and the port 5060 will ring.
Situation 3: Call from an IP phone to a station (IP Tel)
1. Go to ‘Port Settings Port Group’ on the WEB interface and click the ‘Add New’ button to
create a new port group and add FXS ports which are connected with stations to it. Refer to

Synway Information Engineering Co., Ltd
SMG Series Analog Gateway User Manual (Version 1.6.4) Page 10
3.6.3 Port Group for detailed instructions. You may use the default values of other
configuration items and are required not to leave ‘Description’ empty.
Example: Provided the FXS port which is connected with a station is Port1, check the
checkbox before Port1, set Index to 1, fill in Description with test, and keep the default
values of other configuration items.
2. Go to ‘Route Settings IPTel’ on the WEB interface and click the ‘Add New’ button to add
a new routing rule. Refer to 3.7.2 IPTelfor detailed instructions. Fill in ‘Source IP’ with the
IP address which initiates the call and select the port group created in Step1 as ‘Destination
Port Group’. You may use the default values of other configuration items and required not to
leave ‘Description’ empty.
Example: Provided the IP address of the IP phone which initiates the call is 192.168.0.111.
Set Index to 63, Destination Port Group to 1, fill in Description with test, configure Source
IP to 192.168.0.111, and keep the default values of other configuration items.
3. Pick up the IP phone and call the IP address and port of the SMG analog gateway to ring the
station.
Example: Provided the IP address of the SMG analog gateway is 192.168.0.101 and the port
is 5060, use the IP phone to call the IP address 192.168.0.101 and the station connected with
Port1 will ring.
Step 10: Enable the auto dial feature. (Skip this step if not necessary.)
Go to the Port Settings interface to enable the auto dial feature and set the parameters ‘Auto Dial
Number’ and ‘Wait Time before Auto Dial’. If there is no dialing operation in a time period (i.e. Wait
Time before Auto Dial) after pickup, the port will automatically call the preset number (i.e. Auto
Dial Number). Refer to 3.6.1 FXS for detailed instructions.
Step 11: Enable the DND (do not disturb) feature. (Skip this step if not necessary.)
Go to the Port Settings interface to enable the DND feature. Then, the FXS port will reject all
incoming calls. Refer to 3.6.1 FXS for detailed instructions.
Step 12: Enable the call waiting feature. (Skip this step if not necessary.)
Go to the Port Settings interface to enable the call waiting feature. Then the corresponding FXS
port while in conversation can accept another call from IP and keep it in the waiting state. Once
the current conversation is finished and the station hangs up, the call in the waiting state will ring
the station and wait for answer. During the time in the waiting state, it will always hear the ringback
tone from the FXS port. Refer to 3.6.1 FXS for detailed instructions.
Step 13: Perform call forwarding. (Skip this step if not necessary.)
Situation 1: Hook-flash operation
Figure 2-4 Call Forward via Hook-flash
As shown above, Remote A initiates and establishes a call with Station. Then by a hook-flash
operation, that is, a rapid clap on the hook or pressing the ‘flash’ button on the phone set, Station
can forward the call to Remote B.
Once a flash is generated, Station will go into the dialing state (the FXS port sends it dialing tones)
before it dials the forwarding number.

Synway Information Engineering Co., Ltd
SMG Series Analog Gateway User Manual (Version 1.6.4) Page 11
If the dialing succeeds, the FXS port will send ringback tones to Station. Provided Remote B picks
up the call, at this time Station can:
a) Directly talk with Remote B;
b) Perform another hook-flash operation to switch the call to either Remote A or Remote B.
c) Hang up to make Remote A and Remote B go into a direct talk with each other.
If the dialing fails, the FXS port will send busy tones to Station.At this time Station can:
a) Hang up to go back to the ringing state; then pick up the call again to recover the talk
with Remote A.
b) Perform the hook-flash operation again without hanging up the call to recover the talk
with Remote A.
Once Station recovers the call with Remote A, it can forward the call again by a new hook-flash
operation.
Situation 2: Automatic call forward
Go to the port setting interface to enable the automatic call forward feature and fill in a forward
number. According to what you set, the SMG analog gateway can automatically forward the
incoming calls on three conditions: unconditional, busy, no reply. Note that this feature is
applicable only to a single port, but not to a port group consisting of more than one port. Refer to
3.6.1 FXS for detailed instructions.
Special Instructions:
The chassis of the SMG analog gateway must be grounded for safety reasons,
according to standard industry requirements. A simple way is earthing with the third pin
on the plug or the grounding studs on the machine. No or improper grounding may cause
instability in operation as well as decrease in lightning resistance.
As the device will gradually heat up while being used, please maintain good ventilation to
prevent sudden failure, ensuring that the ventilation holes (see Figure 1-8) are never
jammed.
During runtime, if the alarm indicator lights up or flashes, it indicates that the device goes
abnormal. If you cannot figure out and solve the problem by yourself, please contact our
technicians for help. Otherwise it may lead to a drop in performance or unexpected
errors.
